Azure Linux In, CentOS Out: LinkedIn Switches its Server Operating System

As part of a massive migration campaign, LinkedIn has successfully moved their operations to Microsoft’s Azure Linux as of April 2024, ditching CentOS 7 in the process and taking advantage of a more modern compute platform.

As many of you might already know, back on June 30, 2024, CentOS 7 reached the end-of-life status, resulting in no new future updates for it, including fixes for critical security vulnerabilities.

…

The developers have gone with the high-performing XFS filesystem, which was made to work with Azure Linux to fit LinkedIn’s use case. In their testing, they found that XFS was performing well for most of their applications, except Hadoop, which is used for their analytics workloads.

When they compared the issues that cropped up, XFS came out as a more stable and reliable choice than the other candidate, Ext4.

…

Additionally, LinkedIn’s MaaS (Metal-as-a-Service) team has developed a new Azure Linux Image Customizer tool for automating image generation, that takes an existing generic Azure Linux image, and modifies it to use with a given scenario. In this case, a tailored image for LinkedIn.

Wow are people dumb. We specifically chose the non-IBM source for continuing updates, so that’s two counterexamples to whatever this chucklenuts is pushing.

But - speaking as someone who’s used RHL since 98 and rhel since 3, el8 is so sketchy and el9 is just not worth it. I’ll do Rocky if I have to do anything, as at least it uses the better packaging - albeit requiring to mimic RH’s use in the dumbest way to date with a version-switching that pretends the method they fucking invented for doing that better doesn’t exist, the same as PCLinuxOS that does it better every day also doesn’t exist.

I just hope PCLinuxOS can get a good oVirt/pve template packered before it loses its opportunity to show off how insanely great it is.

Red Hat SEVERELY shot themselves in the foot. This sort of thing is just going to continue.

So, somebody that was generating no revenue for Red Hat is not generating revenue for Red Het? Sounds like a real catastrophe for them.

Also, if I had to guess, I would say that Azure Linux is based on CentOS Stream. So, whatever “halo” they had before is mostly still in place.

Most importantly though, LinkedIn is owned by Microsoft as is Azure Linux. So I am not sure what kid of bellwether this is.

Are they most using Azure Linux? Or Azure? If Azure, no headline. If they are not using Azure, why not? That would be the headline here.

At first I read this as “Arch Linux In” and I was like !!?

Does Microsoft contribute to Linux in no evil ways?

friend_of_satan ,

Microsoft has had an impressively positive impact on Linux, including the kernel directly. It started ramping up about 15 years ago. They were the 5th highest contributor to the 3.x kernel.

I recall reading about them working on improving Linux’s MS related features, like fat32 support, samba, and things to make Linux run better in hyper-v that also helped performance overall.

Did you catch that a Microsoft employee found the xz exploit?

Depends how you define evil? If you mean they’re continuing to Linux in an effort to ensure it works well in their Azure platform which they can charge money for using, then yes?

They’re making all the right decisions though, they know that there is great demand for Linux in the server market, and are happy to allow it to run on their cloud platform to ensure viable competition with the other big players (AWS & Google).

Then in turn, their contributions benefit the open source community as a whole.

The fact they’ve also made .NET Core cross platform and another step in the right direction, as well as making VSCode cross platform too.

What would be nice is if they made desktop Office available. It’s one of the few subscription models that would probably work out well for them as many businesses would probably be happy to run Linux clients with native Office 365 support.

I’m genuinely curious. I’ve learnt to never trust Microsoft when they do something “nice”. In my experience they work the long con. I have learnt to never trust them initially. Free windows licenses?, fairly decent Windows 10 initially? This is the last windows 10 version, we’ll keep improving? History can be a bitch.

All valid points.

I believe in this instance, it’s mainly because they have figured out a way to profit off Linux and that is via their cloud hosting platform. As long as they’re making money, it’s probably fine.

They should’ve moved to Windows

KomfortablesKissen ,

Why would they? They know how it’s made!

That’s the point.

They remember what happened when they migrated Hotmail to Microsoft Exchange.

I have no love for linkedin, I’m pretty much forced to be on it though

Microsoft owned company migrates from third party EOL OS to Microsoft distributed OS. No surprise.
